EMANUEL KAUFMANN AND ROBERT J". HOLT, OF ATLANTA, GEORGIA; SAID HOLT ASSIGNOR ;TO SAID KAUFMANN.

MOUNT FOR SEATS.

To all whom it may concern:

Be it known that we, EMANUEL KAUF- MANN and ROBERT J. HOLT, citizens of the 'United States, and residing at Atlanta, in

the county of Fulton and State of Georgia,

have invented certain new and useful Imconnections, as for instance, seats for opverators of machines, telephones, scholars,

etc., in which it is the purpose to provide for various positions to :suit the conditions of the individual, and it is to this type of seat mounts that the present invention pertains.

' Among the objects of ourinvention are to I provide a construction which may be in the 1 form of an attachment for supporting legs,

etc., and whichwill permitthe user of the seat toprovide for swinging pivotal movements thereof either when in or out of position on the seat, and which will provide for a limitation in; the swinging movement; to

provide a construction in which the swinging movement of.the mount may be limited .in one direction, such limitation providing for a limiting in either of two positions at will, thereby enabling the operator to swing the seat to a'convenient position for seating purposes and then restricting the length of swung to the path of free movement of the seat which will have the effect of tending to retain the I seat in position and not require the operator topersonally attempt to hold the seat in such made at a relatively low cost.

position;- also to -provide a' construction. which Is simple and efiic ent n operation, durable in construction, and which can be To these and other ends,.the=nature of which will be readily understood as the .inventionis hereinafter disclosed, said invent on consists in the lmproved construction and comblnation of parts hereinafter fully described, illustrated in the accompanying'drawings, and more particularly 7 pointed out in the appended claims.

In the accompanying drawings, in-which Specification of Letters Patent. Patented Aug. 31, 1915. App1ication filed February 3, 1913. 3 Serial No. 745,940. .7

similar reference characters indicate similar parts in eachof the views: Figure 1 is a top plan view of a seat and its mount secured to a table leg, the seat and its mount being shown in its normal position of use in full lines, and in positions to which it may swing in dotted lines. Fig. 2is an elevation of the same. Fig. 3 is a detail sectional view showing the manner in which the mount is secured to the leg. Fig. 4 is a detail sectional View taken on the line H of Fig. 1.

The present invention is particularly adapted for use in connection with the subject matter of the application of Emanuel Kaufmann, filed February 3, 1913 Serial No. 74:5,937 in which there is a disclosure of means for'providing a support for a plurallty of machine heads adapted to be operated individually, and in which each mathe drawing as angular in cross section, al-

though this particular form is not material, I

the leg being provided with a plurality of means ofwhich a bracket 12 may be secured to the leg-in'any one of a plurality of positions.

p In the drawings, we have shown a plate 10 as interposed betweenjthe bolt heads and the leg, but it is to be understood that any desired form of securing means may be employed for securing the bracket 12 to the .leg, as long as the means'employed is of. sufficientstrength'to prevent breaking of the connection whenthe seat is in use, the lever-- age provided placing a pressure on this form of connection. For the purpose of aiding, in this: respect, we preferably providethe bracket'with a lateral extension 12* which is adapted to extend around to an adjacent side of the leg, this projectingportionor extension tending to prevent a tilting movement of the parts and a tendency to shear the bolt connection. p

The bracketis provided with a pair j, of ears12? having alined openings for the pass fa b l 13 onew hl s mounted. an

, openings 10 for the passage of bolts 11 by arm 14, said arm being mountedltoiswingv with the bolt as its vertical axis.

The arm 14 has its outer end formed .to receive a seat member 18 to which is attached the seat 16, the construction of this portion of the arm being shown as of the gener al,

' with a face l4 inclined to the general direction of length of the arm and to which is pivotally secured a latch member 15, said member having a projection 15 which is adapted to overhang the arm for the purpose of limiting thedownward movement of the latch. The free end of the latch is adapted to cooperate with a lug 12 of the bracket 12, said latch in this position, forming a stop to limit the outward swinging movement of the seat. This is the position shown in full lines in Fig. 1, and practically forms the preferred position in which the operator is seated when operating the machine. Inthis position,the limiting of the movement outwardly, provides an arrangementwhich aids the'operator in that he or she is not required to attempt to hold the arm against outward movement.

As will be obvious, and as disclosed in the dotted line position A of Fig. l, the arm and its seat can be freely swung in the opposite direction, thus placing the seat in a position under the table and out of the way.

As will be clear, the position of the arm in use is such as to make it inconvenientfor the operator to beseated or to pass out of the seat. 'During these operations, the latch 15 is raisedon its pivot, thus temporarily removing the stop action provided thereby,

' and permitting the arm to swing outwardly also forms a convenient support for a until the face, 14 contacts with ,the lug or projection 12,this being the position shown in dotted linesat B in Fig.1, in which po- 'sition the seat portion is projected. out- 'wardly at a convenient point where the operator can readily pass to or out of seating position. After becoming seated, the arm is swung toward the table and the latch dropped, placing the parts-in the proper posit-ion for use. p

5 As shown indotted lines in Fig. 1, the arm bracket 17 to which may be secured any suitable accessory container, thus placing the accessories at a positionwhere they will not be disturbed accidentally,'and" convenient to the operator at all times. The advantages of this particular conviding for maximum efiiciency in use.

While'theinventionis capable of use with any preferred form of mounting for the seat indicated conventionally at 18, we pre fer to employ a construction which will tending to still further steady the seat with out, however, entirely eliminating the pivotal movements, it being understood that the opposing walls of. the open sided bearing,are adapted to abut against-opposite side faces of the arm when the seat is moved pivotally. The specific structure of this par ticular part of the invention is not claimed herein, as the same forms the subject matter of a companion applicationfiled by us F ebruary 3, l913,Serial No. 745,942.

' By this arrangement, it will be understood that there is provided not only a limited swinging movement of the arm itself, but also a limited pivotal movement of the seaton the arm, the result bein that the position of the user of the seat is fixed within reasonable limits and acts to restrict unnecessary movements of the user. This particular feature is not only of advantage in connection with machine supports, but in other respects as well, for instance, as a mount for the seats of school children, especially'those ofearlier age, wherein the positioning of the seat as shown in full lines in t Fig. 1 practically places thechild in proper position with respect to the desk while the limiting of the pivotal movement of the seat prevents the child from moving the seat pivotally on its support in such manner as to materially change its position, although there is a freedom in such movement sufficient for the needs of the child.

WVhil'e we have herein shown and described several ways in which our'invention may be carried out, it will be readily under-i.

stood that changes and modifications there-' in may be required or desired to meet the exigencies of use, and we therefore desire to be understood as reserving the right to make any and all such changes and modifications.

as may be found necessary to meet. these .conditionsinso far as the same may fall within the spirit and scope of the invention as expressed in the accompanying claims.

' Having thus described our invention, whatwe claim as newis: 1. The combination with a stationary sup port, of a bracket secured thereto, an arm pivotally-secured to said bracket and having a lateral, projection, a latch pivotally se,
